Abstract

A novel catalytic approach related to the enantioselective fluorination reaction using N-fluoroammonium salts of cinchona alkaloids which produces non-racemic α-fluoroketones is described. Acyl enol ethers of ketones 1 are enantioselectively fluorinated with Selectfluor® in the presence of a catalytic amount of cinchona alkaloid and 1.2 equivalents of sodium acetate at room temperature for 1–3 days to furnish α-fluoroketones 2 in good yields and moderate enantioselectivity (up to 54% ee).
